Reset: use ref-counting to own subsystems.
Change the subsystem-group and manager code to use shared-ptr references
to subsystems, instead of holding a raw pointer. Hence the manager becomes

track-to animation: 2dof rotation for slave object.
Slave objects can now rotate around two axis to always track the
target - even when it is outside the plane perpendicular to the
lock-axis of the root object. This allows for example animating
levers with non-parallel axis of rotation connected with a rod.

Avoid a divide-by-zero on malformed BTG files.

- implement pow, tan, acos and asin natively

option precision. I.e you can round(479, 50) and get '500'; useful

Expose active tiles via API, sync by SGBucket.
Provide an API to query which tiles are currently being synced. This
allows the higher levels (TileManager in FlightGear) to safely wait on
TerraSync before loading tiles.
Doing this exposed some bugs in scheduling tiles to sync by integer
lat/lon, related to round-towards-zero with -ve values (western /
souther hemispheres). To resolve these, and also reduce spurious
syncs, switch to an explicit API for requesting tiles by SGBucket.
This keeps TerraSync fully aligned with the TileManager queue, which
has many benefits for both high and low visibility situations.
